Tree diversity of the Dja Faunal Reserve, southeastern Cameroon.

The Dja Faunal Reserve located in southeastern Cameroon represents the largest and best protected rainforest patch in Cameroon. Here we make available a dataset on the inventory of tree species collected across the Dja. For this study nine 5 km long and 5 m wide transects were installed. All species with a diameter at breast height greater than 10 cm were recorded, identified and measured. A total of 11546 individuals were recorded, corresponding to a total of 312 species identified with 60 genera containing unidentified taxa. Of the 54 identified families Fabaceae, Rubiaceae and Malvaceae were the most species rich, whereas Fabaceae, Phyllantaceae and Olacaceae were the most abundant. Finally, Tabernaemontanacrassa was the most abundant species across the Reserve. This dataset provides a unique insight into the tree diversity of the Dja Faunal Reserve and is now publically available and usable.

Introduction

Tropical rainforests are among the most diverse plant communities worldwide and contain more than 50% of the Earth’s species diversity (Parmentier et al. 2007). Rain forests are remarkable by the diversity of tree species they contain, in places reaching up to 300 different species within a single hectare of inventoried forest (Valencia et al. 1994). Yet inventory of species in tropical countries remains challenging (Campbell and Hammond 1989). The Republic of Cameroon, situated on the Atlantic Coast in the Gulf of Guinea, covers 475440 km² and has such a great diversity of habitats that it is often compared to "a small Africa".

Although Cameroon has been better explored by botanists than most of other Central African countries (Letouzey 1968), its flora remains incompletely known, and several new species are described or newly recorded every year (e.g. Cheek 2009, Droissart et al. 2009, Lachenaud and Séné 2012, Sonké et al. 2009, Lachenaud et al. 2013). This is partly due to the high botanical diversity of the country (e.g. Kenfack et al. 2007) which includes many endemics (Onana 2011). In addition, botanical efforts have tended to focus on some specific sites (e.g. Mt Cameroon, Bakossi mountains, Campo Ma'an National Park; Cheek et al. 2004, Cable and Cheek 1998, Tchouto et al. 2006), leaving other areas almost unexplored, especially in the west and southeast (Onana 2011, Droissart et al. 2012). The present contribution publishes the results of an inventory made some years ago in the Dja Faunal Reserve, a UNESCO World Heritage Site, located in southeastern Cameroon. Its altitude is between 500 and 700 m and covers an area of 526,000 ha mainly classified as moist evergreen tropical forests  (Letouzey 1985) and belongs to the Guineo-congolian phytochoria of (White 1979). It is bounded on three-quarters of its periphery by a natural barrier that is the Dja river. The reserve also belongs to the TRIDOM forest block that encompasses several other major reserves such as Odzala National Parc in the République du Congo and the Minkébé Natinal Parc in Gabon. This region is characterized by a low collection density of botanical specimens and are thus fragmentarily known (Valkenburg et al. 1998, Onana 2011, Droissart et al. 2012).

The present dataset was available only under printed form (Sonké 2004, Sonké 1998). Here we make it available open access under electronic form. This dataset has been used to assess the role of dispersal and niche differentiation in explaining species distribution across the reserve (Hardy and Sonké 2004).

Study area description

The dataset contains tree inventory of nine 5 km long 5 meters wide transects across the Dja Faunal Reserve. The Dja Forest Reserve is situated at 2°50 – 3°30 N and 12°20 – 13°40 E in southeastern Cameroon, bounded on three sides by the Dja River (Fig. 1), a major tributary of the Congo river, within the area known as the southern plateau. Most of the Dja Faunal Reserve is situated at 600–700 m above the sea level and covers 526,000 ha making it one of the largest and best protected areas of lowland rainforest across tropical Africa. The monthly average temperature lies between 23.5 °C and 24.5 °C and the annual rainfall between 1180 mm and 2350 mm. There are four major vegetation types in the Dja: primary terra firme primary forest (74% of total individuals collected occurring in this vegetation type); (ii) secondary forest (8% of total individuals); (iii) gaps (4% of total individuals). Finally, two hydromorphic types were defined as (iv) swamps (11%) and (v) flooded forest (3%). The different vegetation types across each transect are provided in Suppl. material 2. Transects were placed at the following coordinates:

There are local Baka people living in the forest practicing subsistence hunting and gathering, thus there is some minimal human pressure on the forest. The forest has its full compliment of large animals, including Western Lowland Gorillas () and African forest elephants () (Dupain et al. 2004).

Funding

Collection of the data in the field was funded by the European Union project ECOFAC.

Sampling methods

Study extent

The dataset was collected between August 1993 and August 1995.

Sampling description

A line transect approach was chosen to sample forest diversity because it covers the heterogeneity of the forest better than a square plot. We used standardized methods to install the transects, identify, map, measure and re-measure the trees (Baker et al. 2004). Each transect line was 5 meters wide and 5 km long. A total of 9 such transects were done at different places across the reserve Fig. 1. All trees ≥ 10 cm dbh (diameter at breast height, 1.3 m or above all deformities, notable buttresses, if present), were identified, mapped, individually numbered with an aluminium tag and nail, and measured with a diameter tape, or estimated if this the correct point of measurement was not possible to reach. Trees were identified up to species level, and in some cases just up to genus level. Voucher specimens were collected and deposited in different herbaria (mainly YA) and in case of any doubt, supplementary material was collected for further identifications.

Quality control

The present dataset was updated to match the APG III classification of angiosperm families (APGIII 2003) and all species names were checked for validity (spelling and authorship) against online databses (http://tnrs.iplantcollaborative.org/index.html, http://ipni.org; http://plants.jstor.org/; http://www.ville-ge.ch/musinfo/bd/cjb/africa/recherche.php).

Step description

The dataset presented here was collected over a period of three years.

Geographic coverage

Description

Data was collected in 9 different sites across the reserve as illustrated in Fig. 1.

Coordinates

13.666667 and 2.833333 Latitude; 12.333333 and 3.5 Longitude.

Taxonomic coverage

The dataset contains a total of 11546 tagged individuals representing 312 total taxa identified to species level (Table 1) belonging to 54 families and 213 genera (a few photos of selected species are provided in Figs 2, 3). For 60 genera some individuals remained unidentified (marked as sp.). This is mainly related to the poorly known taxonomy of those genera or lack of appropriate material (e.g. flowers) to provide a definite determination. The raw data is available in Suppl. material 1.
